Saudi Arabia worried about 9/11 lawsuits bill in U.S

Saudi Arabia's foreign ministry has said it is a matter of "great concern" that 9/11 relatives in the US may be able to sue the kingdom for damages.

On Wednesday the US Congress voted for a law allowing families of nearly 3,000 people killed in the attacks to sue.

In doing so they overrode a veto by President Barack Obama, who said it would set a "dangerous precedent".

Fifteen of the 19 hijackers that day were Saudi nationals, but the kingdom has denied any role in the attacks.

In a statement, the country's foreign ministry said: "The erosion of sovereign immunity will have a negative impact on all nations, including the United States."

Their argument parallels the one made by Mr Obama. He said on CNN after the vote that the law set a "dangerous precedent" and could lead to the US being opened to "a situation where we're suddenly exposed to liabilities for all the work that we're doing all around the world and suddenly finding ourselves subject to private lawsuits".

Buyers' remorse

Meanwhile, leaders of the Republican party in Congress have said they want to reconsider the law. The Senate majority leader Mitch McConnell admitted that lawmakers had not understood the possible consequences of the legislation.

"Everybody was aware of who the potential beneficiaries were but nobody really had focused on the downside in terms of our international relationships,'" Mr McConnell said.

The White House spokesman Josh Earnest said it was "a pretty classic case of rapid onset buyer's remorse".

The right thing to do

On CNN, Mr Obama also suggested that that voting patterns in Congress were influenced by political concerns.

"If you're perceived as voting against 9/11 families right before an election, not surprisingly, that's a hard vote for people to take," he said.
